Dental sealants are a kind of protective coating, which is made up of tinted or transparent plastic. It then painted onto the chewing areas of the back teeth, where the possibility of cavity formation is more in comparison to other regions of the teeth.
The major use of sealants is on children’s teeth in order to prevent cavities at an early age. They are not only effective in function but are affordable and normally covered by dental insurance as preventive treatment. Dental sealants cost much less than the amount spent on having filling due to cavities.
